Been a long time,,,,,

I use to use this site after my first TQR in my right leg, that was back in January of 2009. Nine months later they found that the surgery was unsuccessful and decided to try again. Last year in May I had a total knee replacement also in the right leg.

About a month ago I started to experience pain again in the right knee and some major buckling. Long story short the quad repair is again failing. Has anyone had to go through this even twice... how much can one leg go through?
